PC to HP 48G infrared communication
I'd like to transfer data (libraries) from a PC to a HP 48G via infrared. I've already built a converter that receives serial data (2400 baud) and forwards it via IR. Sending ASCII data from the PC and receiving it via SRECV on the 48G works fine. But it seems that I lack the necessary knowledge to use Kermit.

What I've tried:

set modem type none
set port /dev/ttyUSB0
set speed 2400
set stop-bits 2  ; my serial adapter is configured for 8N2 and with just one stop bit the input buffer overflows
set carrier-watch off
set flow-control none
set parity none
set block-check 3
set control-character prefixed all
set file type binary

send FILE.lib

This is based on various tutorials that I found online, for example this one. But I'm not completely sure how to configure the 48G. I've set it to IR, binary, 2400, parity none, cksum 3 and then starting the kermit server via RS Right.

So my question is: How do I configure ckermit (9.0.302) and the 48G for this simplex connection to transfer libraries with error correction?

edit: If I SRECV the stuff from Kermit I get 36 bytes with "…kermit…" in it.
